In order to use Quantum with devstack (http://devstack.org) you'll need to add "quantum" and "q-svc" to ENABLED_SERVICES in your localrc. See this page for more details on localrc settings: http://devstack.org/stack.sh.html.
If you want to enable the openvswitch plugin, you'll have to set Q_PLUGIN to "openvswitch" and also add "q-agt" to ENABLED_SERVICES in order to start the openvswitch quantum agent (also in your localrc).
For example:
ENABLED_SERVICES="g-api,g-reg,key,n-api,n-cpu,n-net,n-sch,n-vnc,horizon,mysql,rabbit,openstackx,q-svc,quantum,q-agt" Q_PLUGIN=openvswitch
Then run stack.sh as normal.
We have a review for running Quantum on multiple nodes: https://review.openstack.org/#/c/7001/
You should run at least one "controller node", which includes at least:
ENABLED_SERVICES="quantum,q-svc" Q_PLUGIN=openvswitch
You can then run many compute nodes, which include:
ENABLED_SERVICES="quantum,q-agt,n-cpu,g-api" Q_PLUGIN=openvswitch
Note: the need to include 'g-api' here seems to be a bug. Without it, nova-compute dies because it can't import the glance.common library.
To enable melange in devstack add "melange" and "m-svc" to the ENABLED_SERVICES (melange requires quantum to be enabled as well).
For example:
ENABLED_SERVICES=g-api,g-reg,key,n-api,n-cpu,n-net,n-sch,n-novnc,n-xvnc,n-cauth,horizon,mysql,rabbit,openstackx,q-svc,q-agt,m-svc,quantum,melange
